ABSTRACT

This investigation was planned with the aim to evaluate different suspensions of certain isolates of bacterium, Pseudomonas fluorescens for their nematicidal potentials against root-knot nematode, Meloidogyne incognita under in vitro conditions. The present results indicated that the tested bacterial isolates at two concentrations (25 and 50%) significantly (p≤0.05) inhibited M. incognita- egg hatching at each exposure period (24, 48, 72 and 96 hrs) compared to untreated control. As for the percentages of the second stage juveniles mortality increased with increasing the concentrations and exposure periods. Generally, the highest egg hatching inhibition and juvenile mortality occurred after 96 and 72hrs exposure to the suspensions of the tested isolates of P. fluorescens depending upon their concentrations and exposure periods, respectively.
